wait_for_bit() wants you to pass a direct address of a 32-bit register. The register I am waiting for is a 16-bit register and the hardware manual doesn't say 32-bit is allowed. When I do a 32-bit read on that address, I actually get a different value.
For example:
=> md.w E8010060 1 e8010060: 0040 => md.l E8010060 1 e8010060: 00400000
So, I can't use wait_for_bit()
Can we somehow extend wait_for_bit() ?
It's a nice function, so it would be good if it worked with more than just 32-bit registers.
However, it's used in 98 places at the moment, so coordinating modifying all those changes at once might be an issue.
